Abstract:The main goal of this study was to evaluate the influence of the number of interrogators in relation to cognitive load and other monitoring between telling the truth, lying or the intention to lie. Earlier research has shown a connection between lying and experiencing cognitive load. Furthermore it is proven that the intention to lie also has an influence on this process. The expectations of this research were that the cognitive load and the score of other monitoring will ascend if someone is interrogated by two interrogators instead of just one. Beside that it was expected that both cognitive load and other monitoring has its highest score if someone is lying, followed by the intention to lie. The expectation that was drawn from this is that the difference between cognitive load and other monitoring increases if people are lying or have the intention to lie, with the presence of a second interrogator. This insight could be used as a basis to optimize the techniques of interrogation. To test the hypothesis, measurements of electrodermal activity (EDA) were taken. The results are showing a tendency towards a difference in cognitive load during the intention to lie, if people are interrogated by one or two interrogator. Keywords: Cognitive load, other monitoring, intention to lie, lying, skin-conductance, police interrogation
